Device for improving reaction efficiency of difluoroethane

The utility model discloses a device for improving difluoroethane reaction efficiency, which relates to the field of reactors, and comprises a reactor, a stirring shaft is coaxially arranged in the reactor, the stirring shaft is fixed at the output end of a stirring device, an anchor stirrer is arranged on the stirring shaft, and the anchor stirrer can scrape off tar adhered on the inner side wall of the reactor. A scraping mechanism is arranged at the bottom of the stirring shaft and can scrape off heavy component substances at the bottom of the reactor, an opening is formed in the bottom of the reactor, and the opening is connected with a slag discharging tank; according to the device, by arranging the anchor stirrer and the scraping mechanism, heavy component substances such as tar in the reactor are scraped off and concentrated in the slag discharge tank, so that the conversion rate of VCM and the service life of a catalyst are prevented from being reduced by the tar generated in the difluoroethane produc
